Many alcoves on Mars resemble glacial cirques on Earth. While some contain glacier-like forms, many do not, and they have never been studied at a large scale. We mapped ~2,000 alcoves in Deuteronilus Mensae and identified 435 as "cirque-like."  These show geomorphic signs of past glaciation and mainly face south–southeast, implying ice accumulation during high obliquity. Further research is needed to confirm the style of glaciation as either warm-based or cold-based. 

Our study examines erosion in a small, pre-Alpine basin by using cosmogenic nuclides in river sediments. Based on a dense measuring network we were able to distinguish two main zones: an upper zone with slow erosion of surface material, and a steeper, lower zone where faster erosion is driven by landslides. The data suggests that sediment has been constantly produced over thousands of years, indicating a stable, long-term balance between contrasting erosion processes.

The Mortuary Temple of Hatshepsut is one of Egypt's key heritage sites but is potentially threatened by rockfalls from a 100 m high limestone cliff. We transferred established monitoring techniques from alpine environments to this UNESCO World Heritage Site and evaluated their performance in a historically sensitive desert environment. Our study presents the first evidence-based event and impact analysis of rockfalls at the Temple of Hatshepsut, providing vital data for future risk assessment.

Bedload transport occurs when a sufficiently strong flow of fluid shears a bed of loose sedimentary grains of millimeter or larger size. Here, we show that a recently proposed artificial numerical method to alter fluid-particle interactions in grain-resolved numerical bedload simulations is physically unrealistic. We conclude, supported by independent modeling, that data created using this method, unlike previously claimed, does not resolve the issue of grain shape effects on bedload transport.

Geomorphologists have more data and computational resources available than ever before, but lack tools to facilitate collaborations needed to integrate data from different modes of study (e.g., field, experimental, modeling). In this article, we discuss challenges to collaboration in geomorphology, and report a new schema for sharing data. The sandsuet schema is designed to accommodate most kinds of rasterized geomorphology data, and makes it easy to package, publish, and share those data.

We explore controls on channel sediment characteristics in post-glacial landscapes. In contrast to other studies that have focused on landscapes with little glacial influence, we find no apparent controls. We propose that Scotland's post-glacial legacy drives the lack of sedimentological trends, and that changes in landscape morphology and sediment sources caused by glacial processes lead to a decoupling between fluvial sediment grain size and environmental variables.

Field measurements of the bedload flux with a high temporal resolution in several Swiss mountain streams were used to analyse the transport variability. The measurements were analysed for short-term transport events typically covering a duration of a few weeks and by considering multi-year annual transport totals. The findings show substantial variability both within and across sites, likely reflecting the influence of sediment availability, stream slope, streambed texture and flow history.

Duricrusts have contributed valuable insight to the evolving field of regolith science over the past two centuries. These mineral-rich layers occur in diverse settings, from hilltops to valley floors, and are thought to form through two main processes. In 2025, we introduced the first numerical model for the hydrological hypothesis; now, we present a complementary model based on laterisation. This framework simulates both the development of duricrusts and their impact on landscape evolution.

Herein, we introduce a new large outdoor river research facility to study how rivers change shape at near-real scales. Initial experiments on a straight channel resulted in little bank erosion even when the flow was perturbed by the placement of an in-channel artificial bar/pool. The results point to a narrow operational window for bar growth and bank mobility which informs on the initial conditions of future bank erosion experiments.
